A "blue moon" has been defined as two full moons in the same month. This can happen in any month except in February. It isn't all that rare; it happens about every other year.
Two "blue moons" in the same year can only happen in January and March, which is what happens in 2018. That's because February is the only month in which it's possible to NOT have ANY full moons; February has only 28 days, and a month is 28.5 days!
We can expect this (two "blue moons" in the same year) about every 31 years; any time the Moon is full on January 2, it will be full again on January 31, March 2 and March 31.

The origin of Once in a blue moon?
Once in a blue moon has come to mean once in a great while, but the actual frequency of blue moons averages about once every 2.7 years, a blue moon being the second full moon in the same month of a solar calendar. That average frequency is exactly the same as the average frequency of a leap month in a lunar calendar. The calculation of the average frequency of blue moons does not take into account that January and March of 2018 will EACH have two full moons, a rarity caused by the fact that February does not last as long as a lunar cycle.

How often is once in a blue moon?
When a single month has two full moons, the second full moon is called a Blue Moon. It happens every 2-3 years. Originally, the Maine Farmer's Almanac defined a "blue moon" as the 13th moon in a tropical year(from winter solstice to winter solstice). Normally, each season would consist of 3 moons. In a season of 4 moons, the third would be considered blue. Blue ink was used to record this event in the almanac. As a reference to the event, though, the idiom "once in a blue moon" means rarely. There is no set amount of time.
